**M1489/87       FinALi-486 PCI Chipset                         <Feb95
***Info:
ALi's M1489/M1487 PCI chipset is  the most cost effective PCI solution
available. M1489/M1487  enables top-to-bottom PCI in  486 CPU systems,
offering superior price/performance for mainstream PCI-ISA systems.

M1489/M1487 highly  integrates the DRAM controller,  L2 cache control-
ler,  Host,  PCI, and  ISA  interface, as  well  as  the standard  ISA
functions:  DMA controller,  interrupt controller,  timer/counter, RTC
(Real Time Clock),  and keyboard controller. Additionally, M1489/M1487
incorporates the high performance Local  Bus IDE allowing a system de-
signer to implement Local bus IDE with no additional cost. M1489/M1487
is a  highly integrated  solution requiring minimized  TTL components,
enabling PCI-ISA designs at costs equal to or lower than comparable VL
Bus designs.

M1489 (Cache Memory PCI Controller:  CMP) integrates the L2 cache con-
troller  and  the  DRAM  controller.  The  cache  controller  supports
write-back cache  policies and cache size  from 128K to 1M  byte in an
interleaved  or non-interleaved  configuration.   The DRAM  controller
interfaces DRAM  to the Host  bus, PCI bus,  and Link bus.   M1489 can
support   EDO  3/5V   DRAM,   standard  DRAM,   and  flexible   timing
select. M1489  also integrates  intelligent Host to  PCI, PCI  to Host
buffer  to achieve high  performance.  Also,  M1489 provides  the high
performance Local Bus IDE interface.

M1487 (ISA Bridge Controller: IBC) provides the bridge between the ISA
bus, PCI  bus, and Host bus.  IBC integrates the  common I/O functions
found in  today's ISA  based systems: a  seven channel DMA,  two 82C59
interrupt controllers,  8254 timer/ counter, deep  green function, and
control logic for NMI generation. IBC also has built-in 128 bytes RTC,
MC14069, KBC,  and 7406.   IBC also provides  the decode  for external
BIOS.
